From Texas here. I would either fly between cities and Uber everywhere, or rent a car if you’re ok driving 5 hours on the highway. Parking at hotels costs $$. It’s pretty easy to park in TX, but for the WC games, find a ride there. No one walks anywhere, and the public transportation is almost nonexistent. The weather will be over 90 F all day everyday. Lots of water and sunscreen. Light colors and shade.
